Best Waterproof Bassinet Sheets

The best waterproof bassinet sheets have a fitted shape that matches your mattress and an integrated moisture barrier. For a common 33 x 17 in mattress, KeaBabies Soothe Protect+ combines a jersey cotton surface with a built-in waterproof layer.

A waterproof bassinet sheet can reduce how often a small spill reaches the mattress, but fit comes first. Measure the mattress and compare its length, width and depth with the sheet’s stated dimensions before you buy.

For broader options by fabric and fit, see our guide to best baby bassinet sheets. If you want to compare standard cotton or organic fabrics, read our guides to best cotton bassinet sheets and best organic cotton bassinet sheets.

How we chose waterproof bassinet sheets

We compared the stated mattress dimensions, barrier design, fabric, pack size and care details. Our score weighs specs and features against the needs of shoppers seeking waterproof bassinet sheets, including whether the barrier is integrated or comes as a separate protector.

A sheet described as waterproof is not automatically compatible with every bassinet. For model-specific options, see Angelbliss bassinet sheets.

Check your bassinet manual and measure the mattress before buying, especially when the product size differs by an inch or more from your mattress.

Waterproof bassinet sheets compared by fit and barrier

The strongest options here include a built-in waterproof layer or a separately included protector, while several other picks are regular fitted sheets. Check both the mattress measurements and the barrier type before comparing fabric or pack size.

Best waterproof bassinet sheets for different mattresses

KeaBabies Soothe Protect+ is the top overall fit for many 33 x 17 in mattresses, while the other options serve different mattress sizes and fabric preferences. The descriptions below distinguish products with stated moisture protection from regular fitted sheets.

1

KeaBabies 2pk Waterproof Bassinet Sheets Girls: Best for 33 x 17 in mattresses

9.6/10Our score

• 33 x 17 in
• Fits mattresses up to 4 in deep
• Jersey cotton with built-in waterproof layer
• 2-pack

The 33 x 17 in size and built-in waterproof layer suit standard mattresses where the dimensions match. Jersey cotton and a stretchy elastic band are designed for a fitted feel.

See it on Amazon

Pros

• Built-in waterproof layer
• Jersey cotton
• Machine washable and dryer-friendly

Cons

• Check mattress dimensions before choosing
• Maximum stated mattress depth is 4 in

KeaBabies Soothe Protect+ is the leading choice when your bassinet mattress measures 33 x 17 in and is no deeper than 4 in. Its cotton jersey surface has a built-in waterproof layer, so the fitted sheet itself provides the stated barrier.

The pair is designed for oval, rectangle and hourglass mattress shapes. KeaBabies describes the elastic SnugFit Bands as helping the sheet stay secure, and the sheets are machine washable and dryer-friendly.

This is a practical pick if you want two fitted sheets and do not want a separate padded protector. Still, compare your actual mattress dimensions with the size before ordering, since “universal fit” does not mean one sheet fits every bassinet.

2

Gllquen Baby Bedside Sleeper Bassinet Sheets 33x20: Best for a 4-pack

9.3/10Our score

• 33 x 20 in
• Microfiber polyester
• 4-pack
• Full-coverage elastic band

This four-sheet set fits a 33 x 20 in bedside sleeper mattress. It does not have a stated waterproof barrier, so pair it with a separate compatible protector if moisture protection is the priority.

See it on Amazon

Pros

• Four sheets in the pack
• Sized for 33 x 20 in mattresses
• Machine washable

Cons

• No waterproof layer stated
• Confirm the mattress size and shape

GLLQUEN BABY’s four-pack is sized for 33 x 20 in bedside sleeper mattresses, making it a useful option when the larger rectangle fits your bassinet. The microfiber polyester fabric is machine washable, and the full-coverage elastic band is intended to hold the sheet around the mattress.

This is not a waterproof sheet based on its stated features. If the moisture barrier matters, use a compatible protector approved for your bassinet, or choose an option with a built-in lining.

Four sheets give you a larger rotation than a two-pack. GLLQUEN BABY also describes the sheets as fitting similarly sized oval or rectangular bassinets, but start with measurements rather than shape alone.

3

Biloban Baby Bassinet Sheets 4 Pack Compatible: Best for rectangular mattresses

9.2/10Our score

• About 33 x 20 in
• Microfiber
• 4-pack
• Fully encased elastic

Biloban offers four soft microfiber fitted sheets for many standard rectangular bassinet mattresses around 33 x 20 in. These sheets do not include a stated waterproof barrier.

See it on Amazon

Pros

• Four sheets in the pack
• Fully encased elastic
• Machine washable

Cons

• Not waterproof
• Measure the mattress before ordering

Biloban’s four-pack suits many 33 x 20 in rectangular bassinet mattresses, including some bedside sleeper models. Each sheet is microfiber with elastic around the full bottom edge, and Biloban recommends measuring the inside mattress dimensions before ordering.

The sheets do not contain plastic and do not have a stated waterproof barrier. That distinction matters if you are specifically shopping for waterproof bassinet sheets: these are fitted covers, not an integrated moisture-protection layer.

Biloban lists machine washing on a cold, gentle cycle and tumble drying on low. The four-sheet pack can help keep a clean sheet ready while another is in the wash.

4

Ely's & Co. Patent Pending Waterproof Bassinet: Best for smaller mattresses

9.1/10Our score

• Fits mattresses up to 32 x 16 in
• Jersey cotton with waterproof lining
• 2-pack
• Machine washable

These two jersey cotton sheets have a waterproof lining and suit bassinet mattresses up to 32 x 16 in. The smaller maximum size makes mattress measurement especially important.

See it on Amazon

Pros

• Waterproof lining
• Jersey cotton surface
• Two sheets in the pack

Cons

• Maximum stated mattress size is 32 x 16 in
• Confirm fit before ordering

Ely’s & Co. is the best fit in this group for a smaller mattress up to 32 x 16 in. Its two jersey cotton sheets have a waterproof lining, combining a soft fitted surface with a barrier against liquids and stains.

The smaller maximum size is the key buying check. If your mattress is larger, do not assume the elastic will make the sheet fit securely; compare its dimensions with the maker’s stated limit.

The brand describes the sheets as machine washable and designed to maintain softness and color through repeated washes. For another fabric-focused comparison, see our guide to best organic bassinet sheets.

5

meowcards Muslin Bedside Bassinet Sheets 2 Pack: Best for muslin feel

9.1/10Our score

• 33 x 20 in
• Muslin cotton
• 4 in pocket depth
• 2-pack

This muslin cotton pair fits 33 x 20 in bedside sleeper pads with a 4 in pocket. It has no stated waterproof layer, so it is best for shoppers who prioritize muslin over an integrated barrier.

See it on Amazon

Pros

• Muslin cotton
• Stated 4 in pocket depth
• Machine washable

Cons

• No waterproof layer stated
• Only two sheets in the pack

The meowcards pair is for shoppers who prefer muslin cotton and have a 33 x 20 in bedside sleeper mattress. It has a 4 in pocket and a full elastic hem, but no waterproof layer is stated.

That makes it a regular fitted sheet rather than a direct substitute for an integrated waterproof cover. If you prefer an extra sheet rotation, the two-pack can keep one available while the other is being washed.

Check that your mattress is the stated 33 x 20 in size. For a boy-themed sheet search, our guide to best bassinet sheets for baby boy covers more options by style and fit.

6

KeaBabies 2pk Waterproof Bassinet Sheets Boy: Best for bamboo-derived fabric

9.0/10Our score

• 33 x 17 in
• Viscose derived from bamboo with waterproof lining
• Fits mattresses up to 4 in deep
• 2-pack

The Isla pair combines a built-in waterproof lining with a 33 x 17 in fit and a maximum mattress depth of 4 in. Check those measurements against your bassinet before choosing it.

See it on Amazon

Pros

• Built-in waterproof lining
• Viscose derived from bamboo
• Machine washable and dryer-friendly

Cons

• Check mattress dimensions before choosing
• Maximum stated mattress depth is 4 in

KeaBabies Isla Protect+ offers a built-in waterproof lining in a 33 x 17 in fitted sheet made from viscose derived from bamboo. The pair fits mattresses up to 4 in deep, so it is most relevant when those measurements match your bassinet.

KeaBabies describes the material as soft and breathable and says the sheets are machine washable and dryer-friendly. The stretchy SnugFit Bands are designed to make the sheets easier to put on and remove while keeping them fitted.

Choose Isla if you want the same general mattress size and barrier style as the top pick, with a different stated fabric. Check the bassinet mattress dimensions and depth before ordering.

7

Knirose Organic Baby Bassinet Sheets 2 Pack: Best for organic muslin

8.9/10Our score

• 33 x 17 in
• Organic muslin cotton
• 6.5 in pocket depth
• 2-pack

Knirose offers two organic muslin sheets with a 6.5 in pocket, but no waterproof layer is stated. Consider them if fabric preference matters more than integrated moisture protection.

See it on Amazon

Pros

• Organic muslin cotton
• 6.5 in pocket depth
• Machine washable

Cons

• No waterproof layer stated
• Measure mattress shape and size

Knirose is the fabric-led choice for shoppers seeking organic muslin cotton, with a 33 x 17 in size and 6.5 in pocket depth. It does not have a stated waterproof layer, so it is not a substitute for a waterproof fitted sheet or protector.

Its fully encased elastic is designed to hold the sheet around the mattress, and the two-pack is machine washable. Knirose describes the fabric as GOTS certified organic cotton, a claim to check against the exact item you intend to buy if certification is central to your choice.

Choose it for the material and pocket depth, not for moisture protection. A snug fit still depends on the bassinet mattress matching the sheet dimensions and shape.

8

Konssy 3 Pack Stretchy Bassinet Sheets: Best for stretch

8.6/10Our score

• 33 x 21 in
• Polyester and spandex
• 3-pack
• Elasticized edges

These stretchy sheets fit many 33 x 21 in bassinet mattresses and come in a three-pack. No waterproof layer is stated, so they are an option for a stretchy fitted sheet rather than built-in moisture protection.

See it on Amazon

Pros

• Three sheets in the pack
• Polyester-spandex stretch
• Machine washable

Cons

• No waterproof layer stated
• Measure the mattress to check fit

Konssy’s three-pack is the stretchy option for mattresses around 33 x 21 in. The fabric is 89% polyester and 11% spandex, with elasticized edges and machine-washable care.

No waterproof barrier is stated, so these are best considered regular fitted sheets. The extra stretch may be useful for a compatible mattress, but it does not make the 33 x 21 in size a match for every bassinet.

Measure the mattress before choosing this set, particularly if your bassinet uses a narrower pad. The product description names several shapes, but the size remains the main fit check.

9

Moonsea Bassinet Sheets & Waterproof Bassinet Mattress: Best for a separate protector

8.3/10Our score

• 32 x 17 in
• Four sheets and one waterproof protector
• Viscose terry protector top
• Noiseless waterproof membrane

Moonsea pairs four sheets with a separate waterproof mattress protector. The protector’s membrane is described as noiseless, while the 32 x 17 in size should be checked against your mattress.

See it on Amazon

Pros

• Includes a separate waterproof protector
• Four sheets in the set
• Machine washable and dryable

Cons

• Protector is separate from the fitted sheets
• Measure the mattress before ordering

Moonsea takes a different approach: it pairs four fitted sheets with one separate waterproof mattress protector. The protector has a viscose terry top and a waterproof membrane described as noiseless, while the sheets themselves are not described as waterproof.

The set is sized 32 x 17 in and is described for oval, round, rectangle and hourglass mattresses. Check the mattress dimensions and bassinet guidance, since a protector and sheet set still needs to fit securely without bunching.

This can suit a caregiver who wants several regular sheets plus a separate barrier. For bassinet accessories beyond bedding, see what a bassinet hood is for and our guide to best Delta Children bassinet sheets.

How to choose waterproof bassinet sheets

Choose waterproof bassinet sheets by matching the mattress dimensions first, then deciding whether you want the barrier integrated into the sheet or supplied as a separate protector. Material and pack size matter after you know the sheet can fit correctly.

What mattress size should waterproof bassinet sheets fit?

Waterproof bassinet sheets should match the mattress length, width and depth closely, with a fitted edge that stays flat. The products here include sizes from 32 x 17 in to 33 x 21 in, so there is no single size that fits all bassinets.

Measure the mattress itself rather than relying on a general bassinet label. If your mattress has a nonstandard shape or the maker specifies approved sheets, follow that guidance.

Is an integrated waterproof bassinet sheet better than a separate protector?

An integrated barrier combines the fitted sheet and moisture layer in one piece, while a separate protector sits beneath a regular fitted sheet. KeaBabies and Ely’s & Co. have stated built-in waterproof layers; Moonsea includes a separate protector.

With a separate protector, a spill may mean changing only the fitted sheet if the protector remains clean. With an integrated sheet, the whole sheet comes off for washing, so pack size and laundry routine can influence your choice.

Which fabric should you choose?

Choose the fabric based on your preference after confirming fit and barrier type. The waterproof options include jersey cotton or viscose derived from bamboo, while muslin and microfiber options here do not have a stated waterproof layer.

For more detail on fabric choices, compare best Guava Lotus bassinet sheets with your mattress dimensions and the bassinet maker’s bedding guidance. Fabric labels alone do not confirm that a sheet fits a particular mattress.

How many sheets do you need?

A two-pack gives you a spare for laundry rotation, while a four-pack offers more ready-to-use sheets. The picks here range from two to four sheets, and Moonsea’s set also includes one separate waterproof protector.

Think about how often you want to do laundry and whether you need a spare barrier as well as spare fitted sheets. A larger pack is useful only if its size fits your mattress.

Verdict: which waterproof bassinet sheets should you pick?

Choose KeaBabies Soothe Protect+ if your mattress is 33 x 17 in and you want a built-in waterproof layer. Pick Ely’s & Co. for a mattress up to 32 x 16 in, or Moonsea if you want a separate protector with several regular sheets.

For 33 x 20 in mattresses, GLLQUEN BABY, Biloban and meowcards offer fitted-sheet options, but they do not state an integrated waterproof layer. Match the dimensions, check your bassinet’s bedding guidance and choose the barrier style that suits your laundry routine.

Frequently asked questions

Are waterproof bassinet sheets safe to use?

Use a fitted sheet that matches the bassinet mattress and lies flat, with no loose edges or extra bedding. Follow the bassinet maker’s instructions for approved bedding and mattress covers.

A waterproof layer does not replace a firm, flat sleep surface or safe-sleep guidance.

Do waterproof bassinet sheets fit every bassinet?

No. Sizes and shapes vary, so measure the mattress length, width and depth, then compare those numbers with the sheet’s stated fit.

A sheet made for 33 x 17 in may not fit a 33 x 20 in bedside sleeper.

Use the bassinet manufacturer’s guidance if you are unsure which bedding is compatible.

Are waterproof bassinet sheets noisy?

Noise depends on the materials and construction. KeaBabies describes its built-in lining as quiet, and Moonsea describes the membrane in its separate protector as noiseless.

Those descriptions are product features, not a guarantee that every baby or caregiver will hear the same thing.

Should I choose a waterproof sheet or a mattress protector?

An integrated waterproof sheet combines the fitted surface and moisture barrier in one piece. A separate protector sits beneath a regular fitted sheet, so you can change the sheet without replacing the protector if only the top layer gets wet.

Choose a setup that the bassinet maker allows and that fits the mattress without bunching.
